With tens of thousands of tests in California still pending, the number of hospitalizations is believed to potentially be an equally, if not more, accurate measure of the state’s progress during the COVID-19 outbreak.

On Monday afternoon, Gov. Gavin Newsom announced two major figures: the number of coronavirus patients in the state’s hospitals had doubled since Friday and those in intensive care units had tripled.

There are now 1,432 patients hospitalized across California and 597 in ICUs, up from 746 and 200 on Friday. That means roughly 20% of the state’s confirmed cases have checked in to hospitals, similar to hospitalization rates seen in other outbreak areas.

“These have long been projected in our modeling,” Newsom said. “As consequence, we have for weeks now been organizing ourselves around the surge that will require roughly two-thirds increase in capacity in our hospital system.”

On Monday, Newsom announced an initiative to support the state’s frontline healthcare workers, calling on retired doctors and nursing students about to graduate to join the workforce. Shuttered hospitals have reopened their doors and temporary beds have been set up across the state, increasing hospital capacity.

The state reported more than 1,000 new confirmed cases of the respiratory illness on Monday, bringing its total to 7,350, according to data compiled by this news organization. Another 14 Californians died, bringing the state’s death toll to 142. The U.S. on Tuesday passed a grim milestone: With 3,170 deaths from COVID-19, according to Johns Hopkins University, more Americans have now died from the respiratory illness than perished on 9/11.

A model from the University of Washington projects California to just skirt coming up short of ICU beds at the height of the crisis. Their data estimates the outbreak will peak just under a month from now, April 27, with nearly 1,900 requiring intensive care units and 12,666 in hospital beds, both short of California’s estimated capacity.
